Better yet: The most consistent source of magic damage in T10 is mitigation irrelevant. it deals a static amount. The rest is mechanics based and dying to it most likely leads to raid wipes anyway.
T12 is the one encounter where I'd say it's possibly bad news to have a DRG but it's raid wide damage anyway so there's constant heals going out from the start. DRGs are still going to have better EHP vs these attacks than, say, both Healers and casters (barring VIT accessories).
I feel like the best way to put it is that a lot of the numbers thrown around are raw damage numbers. For instance, I need roughly 6000 HP to survive an attack in Phase 3 of T11. Sacred Soil and Succor + natural HP gets me there. If I can gear beyond 6k, I'll survive without it.
It's not really cheesing it, per se, but that target HP numbers can, and often do, include Stoneskin / Adlo for figuring out how to get to it. Getting to that number _without_ them is the goal, however, since it alleviates healer burden.
That said, there's still plenty of attacks that I'd be overkilled so hard by without a full debuff and buff setup anyway that I'm pretty sure I'll never reach a VIT level to survive it otherwise.
